ACK. Quoting the trace again:

What I found interesting is that the kernel hangs at wait_barrier. I
only know the term "barrier" from filesystems. I googled a bit for
barrier+cryptsetup and barrier-md-raid but didn't find anything that
helps.
Searching for "kernel hang at wait_barrier" revelas a few kernel bugs
that might be related. I guess it's a software problem.
